Sensor-Layout Optimization Method Based on a Projectile Positioning Accuracy Analysis
The rapid and accurate localization of impact points of supersonic projectiles on a target surface is a crucial factor influencing the performance of intelligent target-reporting systems.When obtaining projectile impact points by establishing an impact model,the sensor layout plays a vital role in determining the accuracy of the projec-tile impacts.In addressing the selection of the optimal sensor-layout method,this study proposes a projectile-im-pact-accuracy analysis method that combines a geometric dilution of precision analysis with optimization algorithms.This is achieved by calculating the area of iso-lines representing high-precision projectile impact points and searching for the optimal sensor layout within a specific range.The proposed method is validated through multiple sets of the-oretical feasibility simulations,simulations with limited impact ranges under real conditions,and extended experi-ments.Results from these experiments reveal the fundamental principles governing sensor layouts for high-precision projectile impact localization.The effectiveness of the proposed projectile-localization accuracy analysis method is demonstrated by the successful selection of high-precision sensor layouts,with the identified optimal sensor layouts aligning with the fundamental principles of high-precision sensor deployment.
